#SOUTHCOM Commander Gen. Francis L. Donovan was honored to meet with Paraguayan President Santiago Peña in Miami today. Discussions focused on joint efforts to combat narco-terrorism in our hemisphere and strengthen the U.S.-Paraguay defense partnership.
Paraguay is a valued member of the Americas Counter Cartel Coalition (A3C) and a true friend to the United States. Their commitment and capabilities are critical to ensuring the safety, security, and prosperity of our citizens.

Jungle training in Peru:
The jungle environment cannot be simulated — its demands on the warfighter are absolute. To fight and win, warfighters must possess rigorous physical conditioning, mental resilience, and unwavering discipline. At the unit level, success requires absolute mastery of small-unit tactics, decentralized leadership, and adaptive logistics.
During Exercise Southern Vanguard in Peru, U.S. Soldiers conducted field and command post training alongside Argentine, Chilean, and Peruvian counterparts. Operating in the demanding, austere terrain of the Amazon, the multinational force simulated real-world contingencies to master this highly complex environment.

A historic milestone in the U.S.-Guatemala security partnership:
For the first time in nearly 50 years, the U.S. has delivered an armaments package to Guatemala.
Financed by Guatemala to advance its military modernization, these assets will directly boost defense capabilities against regional drug trafficking and organized crime. This delivery reinforces Guatemala's vital role within the Americas Counter Cartel Coalition. @DeptofWar @SecWar @WHAAsstSecty
Por primera vez en casi 50 años, Estados Unidos entrega un paquete de armamento a Guatemala, un hito histórico en la alianza de seguridad bilateral. Esta entrega es financiada por Guatemala como parte de una política de modernización militar que entre 2024 a 2027, superará los 85 millones de dólares en ventas desde Estados Unidos, además del proyecto de infraestructura del Cuerpo de Ingenieros del Ejército de Estados Unidos. Esta inversión histórica refleja el firme compromiso de Guatemala con el fortalecimiento de sus capacidades de defensa, y de unirse a los Estados Unidos en poner fin al crimen organizado y el narcotráfico en la región.

🚤🇺🇸🇨🇷 Lanchas interceptoras SAFE Boat de alta velocidad y fabricación estadounidense reforzarán la capacidad de Costa Rica para perseguir e interceptar embarcaciones utilizadas para el narcotráfico en alta mar.
La nueva Ley de Seguridad Portuaria de Costa Rica establece un marco de trabajo para que el país refuerce su seguridad marítima y comercial y para proteger vitales cadenas de abastecimiento.
La embajadora Hildebrand acompañó a la presidente Laura Fernández en Golfito para la entrega de las interceptoras y tres vehículos de apoyo al Servicio Nacional de Guardacostas y su Grupo de Operaciones Especiales (GOPES). En lo que va de 2026, estas fuerzas han incautado aproximadamente 44 toneladas métricas de drogas ilícitas en su lucha contra las organizaciones criminales que amenazan las aguas costarricenses.
🤝 Esta donación y la nueva ley fortalecen la cooperación entre Estados Unidos y Costa Rica para proteger los mares del país, evitar que las drogas ilícitas lleguen a Estados Unidos y debilitar a las organizaciones criminales que amenazan la seguirdad de nuestro hemisferio. #ÉxitosEnSeguridad
